Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, radio resource control signaling configuring an uplink transmission configuration indication (TCI) state pool that includes multiple candidate uplink TCI states associated with an uplink resource. The base station may transmit, and the UE may receive, downlink signaling that identifies, among the multiple candidate uplink TCI states included in the uplink TCI state pool, an uplink TCI state to be used to transmit an uplink communication on the uplink resource. Accordingly, the UE may transmit, to the base station, the uplink communication on the uplink resource using an uplink transmit beam based at least in part on the uplink TCI state identified in the downlink signaling. Numerous other aspects are provided.

Abstract: Inter-cell mobility across serving and non-serving cells based on layer 3 measurements is accomplished at the cost of increased delay. Inter-cell mobility across serving and non-serving cells based on layer 1 measurements minimized delay. A user equipment (UE) apparatus that is served by a serving cell of a base station receives, from the serving cell, a configuration to perform layer 1 (L1) measurements based on one or more reference signals from a non-serving cell. The UE also receives the one or more reference signals from the non-serving cell. The UE performs the L1 measurements on the one or more reference signals received from the non-serving cell based on the configuration received from the base station. The UE may perform the L1 measurements on a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), or a positioning reference signal (PRS) from the non-serving cell.

Abstract: Certain aspects of the present disclosure provide a method of wireless communication by a user equipment (UE), generally including receiving signaling configuring the UE with a set of candidate cells, receiving, from a serving cell, downlink control information (DCI) indicating one candidate cell of the set of candidate cells as a target cell for transmitting a physical random access channel (PRACH), and transmitting the PRACH in the target cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive scheduling information for an uplink shared channel transmission, the scheduling information indicating multiple transmission configuration indicator (TCI) states. The UE may transmit a first portion of the uplink shared channel multiplexed with uplink control information (UCI) using a first set of resources and in accordance with a first TCI state. Similarly, the UE may transmit a second portion of the uplink shared channel multiplexed with UCI using a second set of resources and in accordance with a second TCI state. The first set of resources and the second set of resources may overlap in time, but not in frequency. A network entity may receive and decode the first portion and the second portion of the uplink shared channel.

Abstract: A user equipment (UE) may be configured to transmit an indication of UE capability to support a cross frequency range/band sounding reference signal (SRS) indication for physical uplink shared channel (PUSCH) scheduling. The UE may transmit the indication of the UE capability to the network node, the indication of the UE capability including an association between a first reference signal (RS) transmitted in a first frequency band and a second frequency band, the second frequency band being different from the first frequency band, transmit the first RS in the first frequency band to the network node, and receive an uplink (UL) grant scheduling a UL channel associated with the second frequency band from the network node, the UL grant being based at least in part on the first RS in the first frequency band.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity associated with a first transmit-receive point (TRP) and a second TRP, an uplink power control configuration that configures a first set of uplink power control parameters associated with the first TRP and a second set of uplink power control parameters associated with the second TRP. The UE may transmit, to the first TRP, a first uplink transmission based at least in part on the first set of uplink power control parameters associated with the first TRP. The UE may transmit, to the second TRP, a second uplink transmission based at least in part on the second set of uplink power control parameters associated with the second TRP. Numerous other aspects are described.
